  schema:description "Depth of invasion is how far down a cancer has grown from the surface it started on, measured in millimetres on the pathology slide; in mouth cancer it now sets the T stage and a depth over 4 mm means the neck nodes are treated even when they look clean, and in early stomach cancer it decides whether an endoscopic removal was enough."@en ;
